CVE-2026-19140
Description
A flaw was found in Google Chrome's GPU component. This use-after-free vulnerability allows a remote attacker, who has already compromised the browser's renderer process, to potentially escape the browser's security sandbox. This escape can be achieved by tricking a user into visiting a specially crafted HTML page.
Statement
This Important flaw in the Google Chrome GPU component allows a remote attacker to perform a sandbox escape. Exploitation requires a prior compromise of the browser's renderer process and user interaction, such as visiting a specially crafted HTML page. Successful exploitation could lead to arbitrary code execution outside the browser's security sandbox.
